| Outline of Final Research Achievements |
Cyclodextrin-based metal-organic Frameworks (CD-MOFs), which are porous organic crystals, were crystallized. Catalytically active noble metals and molecules were efficiently introduced into the nanopores of the CD-MOFs by adsorption and co-crystallization methods. CD-MOF with palladium nanoparticles showed high catalytic activity for the Suzuki coupling reaction, and even with 1/25 of the catalyst amount, the catalytic activity was similar to that of commercial Pd/C catalyst. When cobalt porphyrin, an organometallic catalyst, was introduced into CD-MOF, it showed almost the same catalytic activity as the corresponding homogeneous catalyst, but the reaction rate decreased due to the intra-crystal diffusion. Finally, CD-MOF with fullerene C60 showed high photocatalytic activity in the hydroxylation reaction of phenylboronic acid.

有機金属触媒や有機分子触媒は医薬系の分野で使用されている。これらの触媒は高価であるため多孔質材料へ高分散導入することで、再生使用することが望まれる。シクロデキストリン系金属有機構造体(CD-MOF)は生体に安全な材料であり、ドラッグキャリアーとしての応用が期待されている。本研究ではCD-MOF内にコバルトポルフィリンやフラーレンC60を高効率、高分散導入する手法を開発し、これらの不均一CD-MOF触媒は均一触媒の触媒活性に匹敵することを明らかにし、医薬系材料開発の触媒として適していることがわかった。
